A groundbreaking study published in the journal Nutrients has shed new light on the nutritional adequacy of the increasingly popular carnivore diet. Researchers, led by Sylvia Goedeke, conducted a case study model to assess the nutrient composition of four variations of the carnivore diet against national nutrient reference values (NRVs).
The carnivore diet, which consists exclusively of animal products, has gained attention for its potential benefits in treating inflammatory conditions. However, concerns about its nutritional completeness have persisted.
“The aim was to assess the micronutrient adequacy of four versions of the carnivore diet against national nutrient reference values,” explained Goedeke.
Key Findings
The study found that the carnivore diet met or exceeded NRV thresholds for several nutrients, including riboflavin, niacin, phosphorus, zinc, Vitamin B6, Vitamin B12, selenium, and Vitamin A. However, the diet fell short in other essential nutrients such as thiamin, magnesium, calcium, and Vitamin C. In some cases, the diet also lacked adequate levels of iron, folate, iodine, and potassium.
Methodology
Researchers developed four meal plans for hypothetical average Australian adults: two female plans and two male plans. One set of plans included dairy products, while the other included offal. The nutrient content was analyzed using dietary software. Goedeke noted, “We developed four meal plans for hypothetical average Australian adults and analyzed them using Foodworks.online dietary software.”

Implications and Concerns
While the carnivore diet met several nutrient thresholds, it significantly lacked fiber, with intake well below recommended levels. This aligns with concerns raised by nutrition experts about the potential impact on gut health. Additionally, the diet’s high sodium content exceeded recommended thresholds, which could have implications for cardiovascular health.
Expert Opinion
Goedeke and her team emphasize the need for further research on the long-term effects of the carnivore diet. “While our study provides valuable insights into the nutrient composition of the carnivore diet, more research is needed to understand its long-term health implications,” Goedeke stated.
As research continues, individuals considering the carnivore diet are advised to consult with healthcare providers before making significant dietary changes. The potential benefits must be weighed against the risks of nutrient deficiencies and other long-term health consequences.
This study marks an important step in understanding the nutritional implications of the carnivore diet, providing a foundation for future research and informed dietary decisions.
